Being a new software paradigm evolved by the Internet, Internetware brings many challenges to the traditional software methods and techniques. Sponsored by the national basic research program （973）, researchers in China have developed an architecture centric technical framework for the definition, incarnation and engineering of Internetware. First of all, a software model for Internetware is defined for what to be, including that Internetware entities should be packaged as components, behaving as agents, interoperating as services, collaborating in a structured and on demand manner, etc. Secondly, a middleware for Internetware is designed and implemented for how to be, including that Internetware entities are incarnated by runtime containers, structured collaborations are enabled by runtime software architecture, Internetware can be managed in a reflective and autonomic manner, etc. Thirdly, an engineering methodology for Internetware is proposed for how to do, including the way to develop Internetware entities and their collaborations by transforming and refining a set of software architectures which cover all the phases of software lifecycle, the way to identify and organize the disordered software assets by domain modeling, etc.

This paper offers a scalable and robust distributed algorithm for decision-tree induction in large peer-to-peer (P2P) environments. Computing a decision tree in such large distributed systems using standard centralized algorithms can be very communication-expensive and impractical because of the synchronization requirements. The problem becomes even more challenging in the distributed stream monitoring scenario where the decision tree needs to be updated in response to changes in the data distribution. This paper presents an alternate solution that works in a completely asynchronous manner in distributed environments and offers low communication overhead, a necessity for scalability. It also seamlessly handles changes in data and peer failures. The paper presents extensive experimental results to corroborate the theoretical claims. © 2008 Wiley Periodicals, Inc.

The Taguchi-based immune algorithm (TBIA), based on both the features of a biological immune system and the systematic reasoning ability of the Taguchi method, is applied in this work to solve the design problem of two-dimensional (2D) recursive digital filters. In the TBIA, the clonal proliferation within hypermutation for several antibody diversifications and the recombination by using the Taguchi method for the local search are integrated to improve the capabilities of exploration and exploitation. The systematic reasoning ability of the Taguchi method is implemented in the recombination operation to select the better antibody genes to achieve the potential recombination, and consequently enhance the TBIA. The design of the 2D filter is reduced to a constrained minimisation problem, the solution of which is achieved by the convergence of the presented TBIA. The computational experiments show that the presented TBIA approach can obtain better results than some previous design methods. © 2008 The Institution of Engineering and Technology.

Respecting related technologies within E-learning domain, the use of Learning management System (LMS) has been considered as the most important and essential component. LMS can manage the curriculum learning content, learner's learning profile and learning process. However it lacks suitable study assistance functions and personalized interface. Accordingly LMS is hard to promote and to be utilized by learners. This paper proposed an integrated framework which combined the personal learning blog functionalities to LMS by using the Tools Interoperability (TI) architecture in order to develop the suitable learning functionalities and interface in LMS for learners. And we hope the TI-based blog functionalities which can be utilized by other LMS in order to improve the LMS utility rate and to prove the feasibility of TI-based blog system. © 2008 IEEE.

Automatic recognition of Source document was the bottleneck of account information system. Artificial neural network was applied in the recognition. Negative data must be the necessary trained samples when training the classifier. The classifier could decrease some kind of recognition error. The error was that refuse recognition was not successful in inputting negative data. The experiment results showed that the classifier could deduce the error and the error rate reach the zero.

New cross language text categorization model based on interlingua semantic

Journal of Computational Information Systems 2008年第1期4卷 105-110页

This paper deals with the problem of Cross Language Text Categorization (CLTC), which arises when documents in different language need to be classified. We propose a new model of CLTC that based on interlingua semantics, which constructs a unified framework to extract the interlingua semantic pairs from the parallel corpus. All these semantic pairs can maximally represent the original cross language information. This interlingua model are exploited to define a generalized similarity function (i.e. kernel function.) among documents in different languages, which is used inside a Support Vector Machines classification framework. The preliminary experiment results show that our models have the potentials for Cross Language Text Categorization.

Data broadcasting is independent of client arrival rate, and thus it is very suitable to transmit popular videos that interest many clients at a particular period of time. One broadcasting method (called periodic broadcasting) is to partition a video into segments, which are then simultaneously broadcast on several data channels. Once clients want to watch the video, they download the segments from these channels. Specially, the skyscraper broadcasting (SkB), client-centric approach (CCA), greedy disk-conserving broadcasting (GDB) schemes were proposed to support a client with a small bandwidth. This paper presents a limited-client-capability broadcasting (LCCB) scheme, which achieves small waiting time, bandwidth consumption, and buffer demand on the client side. In comparison with SkB, CCA, and GDB, LCCB gains smaller waiting time. Extensive simulation results indicate that LCCB also requires lower client buffer spaces than SkB, CCA, and GDB.

Hierarchical genetic algorithms (HGA) as a tool for a search and optimizing methodology has now reached a mature stage. The minimum resource facility to carry user traffic which is called a channel unit (CU) is composed of the IEEE 802.16 medium access control (MAC) protocol. The control of the number of CU depending on traffic load solves heterogeneous and asymmetrical traffic problem in 4G system. In a cellular network, the call arrival rate, the call duration and the communication overhead between the base stations and the control center are vague and uncertain. Whether the criteria of concern be nonlinear, constrained, discrete or NP hard. In this paper, the HGA is used to tackle the neural network (NN) topology as well as the fuzzy logic controller for the dynamic CUs allocation scheme in wireless access net-works. Therefore, we propose a new efficient HGA CUs allocation (HGACA) in cellular networks. It aims to efficiently satisfy their diverse quality-of-service (QoS) requirements of multimedia traffic. The results show that our algorithm has lower blocking rate, lower dropping rate, less update overhead, and shorter channel acquisition delay than previous methods.

Service-oriented computing is becoming a direction of computing technology. For realising the mission of serviceoriented computing, service-oriented architecture has been proposed to facilitate the application development via discoverable services distributed on Internet. That brings out service-oriented modelling as a new technical area to provide modelling and analysis techniques of service-oriented applications. The paper proposes a framework for agentbased service-oriented modelling. It treats both the service providers and the service requesters as service agents. Domain ontology has been used to provide the sharable domain knowledge as well as terminology for allowing the agents to understand each others. A modelling process has also been illustrated with the model development of an online auction service. © 2008 IEEE.
